A simple test on Linux with JACK shows that Pd doesn't clip audio that
exceeds -1 to 1:

Other API may be different, and the driver may clip (or do other
dynamics processing) before sending to the hardware.

I tested with a less current version:

$ pd -version
Pd-0.47.1 ("") compiled for Debian (0.47.1-3) on 2016/11/28 at 20:56:10 UTC

-1 to 1 is the maximum range for floating point audio samples. there's nothing 
else you can do than clipping if you exceed that range.

[PD] Is Pd clip the audio output?

2017-10-19 Thread Nicolas Danet 
Hello, 

In the "A02.amplitude.pd" example it is claimed that:

"Amplitudes of audio signals can have any reasonable range, but when you output 
a signal via the dac~ object, the samples should range between -1 and +1. 
Values out of that range will be clipped."

Is that still true in current version (Pd-0.48-0)?
